BIG time property tax.
Yes indeed. Several years ago I lived in El Paso, population at the time around a half million. Its one public hospital, Thomason, is supported by county property taxes, and under the Texas Constitution has to provide care to everyone who walks through the doors, including any and all of the 1.5 million living in Cd. Juarez across the river in Mexico. County taxpayers pick up the bill at enormous cost. Also, every pregnant woman in Juarez would wait until she was going into labor, cross the border and have the taxi take her straight to Thomason so her new baby would have birthright citizenship and all its entitlements, while she moved to the front of the line to immigrate because of her relationship to her new citizen baby. There was no accounting done. The County Commission one time tried to sue the federal government because of the burden of maintaining Thomason for an entire Mexican city, but had no luck.
